Like characters of reference on. the various figures of the drawingsindicate like elements or features of construction herein referred to. Y

The numeral 1 indicates the wall of a building and 2 the floor line ofaroom in the building, the wall having an aperture 3 therein adjacent tothe floor and usually below a window casing 4 at which a radiator issuitably arranged upon the floor. The radiator comprises a suitablenumber of sections 5 and end sections 6 and 7 connected together, theend sections having the customary supporting legs. The radiator may beadapted either for a steam or a hot water heating system.

The improved ventilator appliance includes a wall-box comprising anouter part 8 adapted to be composed of cast iron and to be inserted inthe aperture 3 and having the usual flange 9 thereon adjacent to theouter end of the part, the part having a squared inner end 10. The parthas suitable storm slats 11 in its outer portion and also a screen 12behind the slats. The outer part has a slanting bottom portion 13 belowthe storm slats and a flat inner end portion 14:, so that the crosssectional area of the inner and outer ends of the part are approximatelyequal.

The. inner part of the wall-box is of improved construction throughoutand comprises a flat bottom 15, two side portions 16 and 17 and a topportion 18, all composed of sheet metal which can readily be cut so thatthe part shall be ofthe required length and have a squared inner end 19to be placed against the end 10 of the outer part. A band 20 embracesand is secured to the inner part adjacent to the squared end 19 in orderto retain the sheet metal in proper of the wall-box is in properposition the bottom 15 extends beyond the inner face of the wall 1 intothe room or compartment, the top portion 18 extending to the inner faceof the wall as do also the side portions 16 and 17. The side portions 16and 17 have preferably flaring portions 21 and 22 respectively that areconnected to the bottom 15, and the top has a preferably flaring portion23 that extends upwardly from the top portion 18 and is connected to theflaring portions of the sides of the part, the flaring portion 23 havinga central aperture 2% therein. The inner end of the inner part of thewallbox is squared so as to have contact with the rear edges of theradiator sections and conduct air to spaces between the sections.

An improved airregulator is provided which includes indicatingcontrolling means and comprises bearingboxes 25 and 26 secured to theinner faces of the side portions 16 and 17 respectively, at pointsrelatively closer to the top portion 18 than to the bottom 15, aregulator damper 27 being pro-- vided which is of suitable size to closethe passageway in the wall-box and has pivot devices 28 and 29 that arearranged near the normal top of the damper and mounted in the bearingdevices 25 and 26 respectively so that the damper is adapted toautomatically close by force of gravity and normally rest against a stopbar 30 which has a base 31 that is secured to the bottom 15. The lowerportion of the damper has a controlling arm 32 secured to the inner sidethereof and extending toward the radiator. A chain 33 is connected tothe arm 32 and extends upward through the aperture 24:, thus arrangedthe chain being behind the radiator and adjacent to the inside of thewall 1. An indicator plate 34 is provided which has an eye 35 on itsnormal lower edge which is connected to the chain 33, the upper edge ofthe plate having an eye 36 thereon. lhe

front of the plate has a sign 37 thereon such as the word @pen toindicate the corresponding position of the regulator. A short chain 38is connected to the eye 36. Another indicator plate 39 is provided whichhas an eye 40 on its normal lower edge that is connected to the chain38, the plate having also an eye 41 on its upper edge; and on the frontof the plate is a sign 42, such as the word Shut to indicate the closedposition of the regulator. A hook a3 is secured to the inside of thewall 1, being preferably secured directly to the window casing 1 so asto be a suitable distance above the plane of the top of the radiator,and either one of the eyes 36 and 11 may be connected to the hook. Theinner end portion of the wall-box, as will be seen, is adapted toconstitute a portion of the radiator casing and air-duct to which otherparts of the casing are connect A. clamp bar at is provided which isarranged upon the bottom 15 adjacent to the inner end thereof and it hasa suitable number of securing bolts 45 connected thereto that extendthrough the bottom 15 and are.

provided with wing-nuts 46 whereby to conveniently connect another partof the radiator casing to the bottom 15.

An improved updraft duct or casing part comprises a front plate 47having reinforcing spacing bars t8 and 48 arranged on its rear or innerside and against the forward edges of the radiator sections 5, the platehaving side edge portions 49 and 50 that extend rearward to the frontsof the end sections 6 and 7 of the radiator. The front plate 47 has acasing bottom 51 integrally connected therewith that extends under thelower ends of the radiator sections between the legs of the endsections, the bottom 51 having a lip 52 that normally extends under thebottom 15 and has slots 53 therein to receive the securing bolts 45between the wing-nuts and the bottom 15, the wing-nuts being screwed upon the bolts to secure the several parts together. A suitable number ofclamp bolts 54 are connected to the bar 48 and the upper portion of thecasing plate 47 and are arranged so as to extend between sections of theradiator and beyond the rear edges thereof, similar bolts 54: beingconnected to the bar 48 and the front plate and so arranged as to benear the lower portion of the front plate. The upper ones of the boltsare connected to a clamp plate 55 and the lower ones to a clamp plate 55that engage the rear edges of the adjacent radiator sections whereby thecasing part is secured to the radiator. Preferably the radiator casingcomprises also a rear plate 56 that rests upon the flaring top portion23 of the wall-box and has side edge portions 57 and 58 that are curvedover to the end sections 6 and i" of the radiator, the rear plate beingarranged against the rear side of the clamp plate 55 and connected tothe bolts 54: by means of nuts 59 with which the bolts are provided.

Constructed as described the rear plate 56 may be loosened and slightlyelevated and, after loosening the wing-nuts 46 the radiator may beeasily moved away from its position for making repairs and may be againreadily returned and the casing connections quickly made, it beingunnecessary to labor ously lift and carry the cumbersome radlator.

In practical use the controlling chain of the air regulator may beeasily drawn upward and the eye 36 connected to the hook at in whichposition the regulator is'fully opened to admit air to the radiator tobe heated; or if less air is desired one of the links of the chain 38may be connected to the hook to hold the regulator in partially openposition When the regulator is closed the its memes eye 41 is connectedto the hook and the sign 42 is visible, the latter being invisiblebehind the radiator When the indicator 37 is drawn up to visibleposition, as represented in Fig. 5. The air entering between thesections of the radiator becomes heated and passes upward from the topof the radiator casing and also out through the openings usuallyprovided in the end sections of the radiator.
